SPECIFICATION forming part of Letters Patent No. 390,333, dated October2, 1888.

Application filed July 27, 1387. Serial No. 245,415. (Xo model.)

To aZZ whom it may concern:

Be it known that I, ABRAHAM M. Baen- RACH, of the city, county, andState of New York, have invented certain new and useful ImprovementsiuAttachments to Time-Pieces, of which the following is a specification.

This invention relates to an improved attachment to Watches and clocks,by which is indicated on the dial Whether the movement has run down andrequires rewinding, so that the watch or clock is wound up at the propertime, and by which, furthermore, the overstraining of the mainspring inWinding up the same is obviated.

rlhe invention consists of an attachment to the movements of watches andclocks, which attachment is operated by the driving meehauism, and whichcomprises a toothed segment that is loosely applied to the arbor of thehour-Wheel, said segment being provided with a smaller segment thatmeshes with a pinion on the arbor ofa pointer that is moved along anauxiliary dial on the face ofthe main dial, said auxiliary dial andpointer indicating at any time the number of hours which the movementhas been ruiming. rlFhe toothed segment and pointer are set to theirinitial or starting position, when Winding up the Watch, by the actionof the spring-barrel and suitable intermediate mechanism, and moved bythe hour-Wheel and suitable intermediate gearing. To permit the settingofthe hands by the handsetting devices without moving at' the same timethe toothed segment and pointer, the segment is moved out of gear withthe motiontransmitting mechanism by the handsetting lever, as will befully described in detail here inafter, and iinally pointed out in theclaims.

In the accompanying drawings, Figure l represents a front elevation of aWatch with my improved attachment for indicating the time which themovement has been running. Fig. 2 is a front view of a Watch-movementwith my improved attachment, the dial being removed and the watch shownin the act of going. Fig. 3 is a detail vertical transverse section online x m, Fig. 2; and Figs. 4 and 5 are top views of the movement withmyimproved attachment, showing the same, respectively, in the act ofwinding it up and in the act of setting the hands.

Similar letters of reference indicate corresponding part-s.

In the drawings, A represents a Watch or clock movement of any approvedconstruction. To the arbor d of the hour-Wheel A] of the same is looselyapplied a toothed main segment, B, which is provided nearer to saidarbor With a smaller toothed segment, Z), concentric to the former. Thetoothed segment?) meshes with a pinion, b, on the arbor bz of a pointeror indicator, b, the arbor passing through the dial D, Which is providedwith an auxiliary dial, D', of semicircnlar or circular shape at thatportion diametrically opposite to the seconds-dial, said auxiliary dialbeing preferably depressed, so that the pointer bf' can move over thesame Withoutinterfering with the hour and minute hands of the movement.

Itis preferable to make the auxiliary dial Dof semicircular shape, asshown in full lines in Fig. l, though it may also be made in eircularshape, as indicated by dotted lines in Fig. l.

rilhe depressed auxiliary dial D" consists of an honrgradnation thatruns up to thirty, forty-tivo, or more honrs, according to the time forwhich the Watch is to rnn. At one end of the dial is arranged thecapital letter S, indicating stop,7 and at the other end the capitalletter XV, indicating wind, which indicatc, when the pointer arrives atthe same, that the time-piece is Wound up sufficiently or that it needsrewinding.

The main segment B is set in motion by a gear-Wheel connection Withthehour-wheel A', so as to move with the movement, which gearA WheelConnection consists of an intermediate pinion, d', a gear-Wheel, d, anda pinion, di, on the arbor oi the gear-Wheel (7F, the pinion dX meshingwith the main segment B, as shown clearly in Fig.2. The arbor ofthegear-wheel d and pinion d3 is supported in bearings of afulcrumed lever,E, which is composed of two parts that are connected by an intermediatespring portion, E', the latter serving to keep the pinion da in meshwith the teeth of the segment B, except when the same is Withdrawn fromthe same while winding up the movement or setting the hands. As the mainsegment B is moved by the gears d d2 cl3, connected with the hour-wheelof the movement, it is obvious that the pointer moves over the auxiliarydial D and indicates clearly the condition of the mainspring-that is tosay, how many hours the same has been running and how many hours it hasyet to run. Vhen the pointer arrives at the opposite end of theauxiliary dial D', the movement is nearly run down and requiresrcwinding. The main segment B has then arrived in the position shown inFig. 4, and has to be returned to its initial or starting position(shown in Fig. 2) by the winding motion of the spring-barrel F and asuitable motion-transmitting mechanism. This mechanism is` interposedbetween the mainspring-barrel and the segment B, and consists of agear-wheel transmission, c' e2 e el, supported 011 a pivoted lever, c,and of a pawland-lever connection, ff, between the barrel ofthemainspring and the fulcrumcd lever E. The gear-wheel transmissionconsists of a gearwheel, e', that meshes with the ratchet-wheel e on thespring-barrel F, the arbor of the gearwheel e carrying a central pinion,e2. This arbor is supported on the pivoted and springactuated lever e3,which is arranged in a depression of the main plate of the movement. Tothe outer end of the lever ci* is attached a shorter arm or bridge, c",that carries an arbor, e5, to which are applied a gear-wheel, e, thatmeshes with the pinion e?, and a pinion, el, that meshes with the mainsegment B when the mainspring is to be wound up andthesegment returnedto its initial position. The bridge e4 is provided with a guard, es,that eX- tendsover the main segment B, and serves as a guide for thesame duringits motion in either direction.

During the winding-up motion of the barrel F the main segment movesinthe direction f, that engages the teeth of the ratchet-wheel c of thespring-barrel F. Theopposite end of the fulcrumed pawl j is pivoted to aconnecting-army, which is guided by a slot, f2, in its opposite end on aheaded screw, f3, at one end of the fulcrumed lever E. This end of thelever E is also connected by a pivot-link, f4, with the lever e3, sothat by the oscillations of the spring-pawlfin following the motion ofthe spring-barrel the connecting-arm j" oscillates the end of the leverE, and nieves thereby the pinion el in mesh with the segment B and thepinion d out of mesh with the same, as shown in Fig. 4. At the intervalsof time during which the spring-barrel in Winding is at rest the piniond3 is in mesh with the main segment B and the pinion c7 out of mesh withthe same, as shown in Fig. 2.

For the purpose of permitting the setting of the hands withoutinterfering with the attachment that indicates the condition of themainspring, the pinion d" has to be temporarily moved out of mesh withthe main segment B, which is accomplished by an arm, El, that eX- tendsfrom the lever E toward the yoke G of the usual stem-winding andhand-setting mechanism of the movement. The yoke G is provided with alug, g, that engages the outer end of tlA arm E2 when the hand-settinglever G is pulled out, as shown in Fig. 5. By pulling out thehand-setting lever G the hand-setting attachment is thrown in mesh withthe gearwheels of the hands, and simultaneously the lug g ofthe yoke Gpressed against the outer end of the arm 2, so that by the spring actionof the middle portion, E', the pinion cl3 is removed from the teethofthe main segment B, as shown clearly in Fig. 5. In this position thetoothed segment B is entirely at rest, and is not moved in eitherdirection while the setting of the hands takes place. As soon as thehand setting lever is returned to its normal position, the arm E2 isreleased and the pinion Z3 returned to its normal position of mesh withthe segment Bby the action of the spring portion E of the lever E.

The attachment described is located below the dial and in full view whenthe same is removed, so that it can be conveniently repaired in case itshould be out of order. The indicating attachment is reset while windingthe movement, and is moved by the mainspring simultaneously with thehands of the movement, so as to indicate at any time the exact state ofthe mai nspring and the exact time when it is necessary to rewind thesame. It also acts as an indicator, by which the straining of themainspriug in winding up the same is obviated, and thereby the iuyuri ngor breaking of the mainspring prevented.

I am aware that it is not broadly new to use in connection with watchesawinding-indicator by which the condition of the mainspring is indicated,said indicator being set in Inotion by the movement from the hour-wheeland returned into its position by a suitable connection with theratchet-wheel of the spring-barrel, and I therefore do not claim thisfeature, broadly, but confine myself to the construction of mywinding-indicator.

Having thus described my invention,I claim as new and desire to secureby Letters Patent-A l.
